I’ve always worn special facial sunblock but could I use this on my face instead?

Or will I be committing a sunscreen no-no?.

Ultrasun

I get through a lot of sunblock every year.

Ultrasun is the dogs'! It is a very good quality sunscreen. I've been using one of their face versions all last summer and my face didn't catch the sun despite the once application only.
If you look up Emma Guns podcast, there is an interesting interview with the founder of the brand which explains about their products formulation

If it's a body spf you might just find it a bit greaser and for me, it makes my eyes v sensitive but you can absolutely use it, spf wise.

I use Ultrasun50 on my face. Love the stuff.

I’m going to try it, I’m trying to get away from chemical sunblocks. I used the facial mineral spf 50 last year but it was too drying, the chemical ones wear off too quickly though and are too greasy.
